Attaching the screen panels

During the course of construction I had been agonizing about how I'll eventually attach the panels to the porch. I wanted to make them removable of course, the reason for all this madness, so I didn't want to just screw them into place.
After some research on different types of hardware, I settled on the brass buttons that you see photographed above. In doing my research on the dilemma, I discovered that these types of buttons were routinely used to hold screens in place when the house was originally built in the 1920's. Because I wanted to bring the house back to its original character, this was a great solution.

Making removable screen panels

Once the main structure was complete, it was time to sit down and make the actual screened panels. For the frame of the panels I used the same 1x2 pressure treated lumber as for the stops described earlier. Because nothing on the porch, or the house for that matter, is square, I had to measure the opening for each of the four sides, for each panel, and label each piece as I cut the lumber, to make sure it would fit in the recessed grove I created. It was a little time consuming but well worth the effort.
Once the pieces were ready, I again predrilled the holes and used trim head screws to put each frame together. Of course there are lots of other ways the frames could have been constructed, but I already had the screws and it was the easiest method for me at the time. I didn't have a biscuit joiner and just wanted to the porch completed already. A one month project is already stretching into the end of the summer.
Once the frames were constructed I had to stretch the actual screen onto them. After trying a few methods, I placed the frames on the garage floor, placed left over pieces of 1x2 along the edges and stapled the screen to the scrap pieces as I stretched the screen over the frame. Once all four sides were done, I stapled the screen to the frame itself.

Installing the spindles

As I was saying before, I wanted to install spindles on the lower half of the porch, mainly for safety, but also so it would match the porch on the front of the house - the one I'll be updating soon so stay tuned.
The stops I installed for the screened panels also served as great nailers for the spindles. That was one of the reasons I decided to go with the stops in the first place. Putting the spindles in place was pretty much what you would expect, although one nice trick I learned was to cut two pieces of wood the same length as the space between the spindles to serve as spacers while installing them. This ended up being a valuable time saver and the spindles went in rather quickly.

The dilemma - screened panels

Since I didn't want to rip up the trim again if I had to replace a ripped screen (the old screen was stapled underneath the trim work), and with a new dog I figured that would be inevitable, I wanted to devise a way to make replaceable screen panels for each of the sections.
Since I had never made screen panels before, or renovated a screened in porch for that matter, I spent a couple of days staring at the structure trying to figure out my best course of action.
I decided to screw pieces of 1x2, again pressure treated of course, lengthwise on the posts that were flush with the outside edge (before adding the new trim), to serve as stops for the panels I would eventually create. Once the new trim was installed, this would create a nice recess area so the panels would be flush with the outside edge. See the photo above that shows the stops after the new trim was installed.
As the wood was thin - I was using 1x2 after all and screwing it in from out outside edge - I predrilled the holes and used trim head screws so I wouldn't split the wood in two when installing the stops.
